To add to your receiver requirements, we all ALSO want the ability to decode 4:2:2 video ( and the increasingly prevalent, Dolby/E audio ) . The perfect reciever is a long way away, I fear. My highest hopes for early adoption of all of these, is in a PCI DVB solution ( that does not yet exist ).
However, even though I'm a long time techie, I think the DVB solution is a strange way to watch TV, so I'm not all that happy with it.
